Yttrium Arsenide is a crystalline solid used as a semiconductor and in photo optic applications.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Yttrium is a Block D, Group 3, Period 5 element. The number of electrons in each of Yttrium's shells is 2, 8, 18, 9, 2 and its electronic configuration is [Kr] 4d1 5s2. In its elemental form Yttrium's CAS number is 7440-65-5. The yttrium atom has a radius of 177.6.pm and it's Van der Waals radius is 200.pm. Insoluble compounds of Yttrium are non-toxic, although water soluble compounds are somewhat toxic. Yttrium has the highest thermo-dynamic affinity for oxygen of any element. This characteristic is the basis for many of its applications. Yttrium is not found in nature as a free element and is almost always found combined with the lanthanides in rare earth minerals. While not part of the rare earth series, it resembles the heavy rare earths which are sometimes referred to as the "yttrics" for this reason. Another unique characteristic derives from its ability to form crystals with useful properties. Yttrium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra high purity); metals in the form of foil, sputtering target, and rod, and compounds assubmicron and nanopowder. Some of the many applications of yttrium include in ceramics for crucibles for molten reactive metals, in florescent lighting phosphors, computer displays and automotive fuel consumption sensors.Yttria stabilized zirconium oxide are used in high temperature applications, such as in thermal plasma sprays to protect aerospace high temperature surfaces and as an electrolyte in solid oxide fuel cells. The name Yttrium originated from a Swedish village near Vaxholm called Yttbery where Yttrium was discovered. Crystals of the yttrium-iron-garnet (YIG) variety are essential to microwave communication equipment. The phosphor Eu:Y2O2S creates the red color in televisions. Crystals of the yttrium-aluminum-garnet (YAG) variety are utilized with neodymium in a number of laser applications. Yttria can also increase the strength of metallic alloys. Yttrium was first discovered by Johann Gadolin in 1794. See Yttrium research below.
Arsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3. The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Due to its toxicity, arsenic compounds are used in insecticides and wood preservation.Arsenic is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Arsenic information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. See Arsenic research below.
An arsenide, an anion with the charge -3, is a rare mineral group consisting of compounds of one or more metals with arsenic (As). Arsenide anions have no existence in solution since they are extremely basic. These solid salts have very high lattice energies and are toxic due to the inherent toxicity of arsenic. Arsenides have applications in semiconductors, laser and light-emitting diodes, quantum dots, and optical and pressure sensors.
